Upload & Sell: Off
If that's what you are using for b&w, it is working. I really like it too, even if I am the only person on the forum who did not take the Sigma deal because I am so stuck on manual lenses.
I didn't buy the Sigmas - too happy with my FDs, Rokkors etc. Next item on my list is an FD Lens Turbo, and I should really get the UWA for the SEL1628...
